Fondaco dei Tedeschi: OMA restored a building whose masterpiece had already gone

In 1508 the outside of the Fondaco dei Tedeschi was the largest public painting in Venice, frescoed by Giorgione and Titian. The sea air destroyed it. Every intervention in the five centuries since has been an argument about what to do with a building whose finest feature no longer exists, and OMA’s answer was the most honest one available: do not put it back.

---

Stand at the foot of the Rialto Bridge today and the Fondaco dei Tedeschi presents four storeys of plain Istrian stone and brick around a courtyard. Handsome, symmetrical, and almost entirely undecorated.

That is not how it was meant to look.

In 1508, the two most talked-about painters in Venice frescoed the outside of this building from top to bottom. Giorgione, then about thirty, took the facade facing the Grand Canal. Titian, then about twenty, took the flank along the Merceria. Both had trained in the workshop of Giovanni Bellini. Their painting wrapped around windows and mouldings in trompe l’oeil, and above the main doorway sat a seated woman holding a sword and a severed head, variously read as Judith or as a personification of Germania.

It was, briefly, the most ambitious piece of public art in the city. And it began to disappear almost immediately.

Vasari, writing in 1550, identified the culprit without hesitation: he knew of nothing more harmful to fresco painting than the sirocco, especially near to the sea. Salt air and humidity did in decades what would have taken centuries inland. By the twentieth century, so little remained that during the restoration of 1937 to 1938 the surviving fragments were detached from the walls altogether. In 1966 they were moved to the Galleria Franchetti at the Ca’ d’Oro, where they still are. What the frescoes actually looked like is now reconstructed from those fragments, from seventeenth century prints, from nineteenth century watercolour sketches by Zaccaria dal Bo, and from Vasari’s description.

So the Fondaco is a building that lost its best feature five hundred years ago, and every architect who has touched it since has had to decide what to do about that absence. OMA, completing an eight-year restoration in 2016, made the most interesting decision of the lot.

Eight hundred years of tenants

The absence is only the start of it. Almost nothing about this building has stayed the same except the site.

Venice bought the land in the 1220s and the German merchants’ trading house, the fondaco, was established here in 1228. A fire required rebuilding in 1318. A far worse one, on the night of 27 to 28 January 1505, destroyed the structure completely.

What stands now is the replacement, put up between 1505 and 1508. The model was drawn by a German merchant known as Girolamo Tedesco. Giorgio Spavento began the work and Antonio Abbondi, called Scarpagnino, saw it through. The plan they built is the reason the building still works: a quadrangular block around a large central courtyard, four levels high, with arcades at ground level for warehousing and floors above for the merchants’ offices and lodgings.

Then the tenants begin to change.

The Republic fell in 1797, and the French turned the trading house into a customs house. The Austrians kept it as an administrative building. After Italian unification, from 1870, it became the central post office for Venice, which it remained for over a century. The restoration of the 1930s rebuilt much of the interior using reinforced concrete, adding a modern structural layer inside a Renaissance shell.

In 2008 the Benetton family’s property arm bought the building for 53 million euros, and in 2009 commissioned OMA.

Read as a list, that is a trading post, a customs house, a post office, a department store and whatever comes next, inside one 1508 envelope. The Fondaco has never been a monument. It has always been infrastructure, and that distinction turns out to be the key to how OMA treated it.

The rule was excavation, not reconstruction

OMA’s restoration of the 9,000 square metre building was led by Rem Koolhaas with Ippolito Pestellini Laparelli and Silvia Sandor, and its governing idea was to treat each intervention as an excavation rather than an addition.

That word is doing precise work. An excavation removes in order to reveal. It does not invent, and it does not put back what has gone. Applied to a building with five centuries of layers, it means the new work is a set of cuts and openings that let you read what is already there, rather than a costume laid over the top.

In practice it produced four moves.

The courtyard was opened to pedestrians. The Fondaco’s central court had always functioned as a covered urban campo, a Venetian square with a roof, and OMA restored that reading by letting people walk into it rather than requiring them to be customers.

New entrances were cut at Campo San Bartolomeo and at the Rialto, joining the routes Venetians already use. A building that occupies a whole block between two of the busiest points in the city had been something you went to. Now it is something you can go through.

Escalators carry a public route up through the building. In a Renaissance palazzo that is an unapologetically modern insertion, and it is the honest one: the alternative is pretending a twenty-first century visitor volume can be moved on sixteenth century stairs.

And a great deal was left alone. Rooms were consolidated to respect the original spatial sequences rather than to maximise floor area, and the historic corner rooms were not touched at all. Knowing where to stop is the part of a restoration nobody photographs.

The roof is the part that changed the city

The single most consequential thing OMA added is at the top, and it is small.

A nineteenth century pavilion on the roof was renovated, a floor of steel and glass was set hovering above the courtyard, and a timber terrace was laid out with a panoramic view across the rooftops of Venice towards the Grand Canal and the Rialto.

Venice is a city almost nobody sees from above. It has no hills, few tall buildings and very little public access to what height there is. A free terrace four storeys up, in the middle of the city, at the foot of its most famous bridge, is therefore not an amenity. It is a new civic viewpoint in a city that had almost none, and it did more to make the building loved than anything inside it.

Together with the courtyard, it also restored something the Fondaco had held for most of its life and lost during the century when it was a post office: a role as a place where the public simply goes.

And the frescoes came back, in another form

Which brings the story back to where it started.

OMA did not reconstruct Giorgione and Titian. Copying lost frescoes onto a facade would have been the obvious gesture and the wrong one, because a reproduction of a lost painting is a claim about the past rather than a contribution to the building.

Instead the galleria walls were given painted decoration again, in contemporary form. The idea is returned rather than the image: this is a building whose interior surfaces are meant to carry painting, so painting goes back onto them, made now and looking like it was made now.

That is the whole restoration in one decision. The layers stay legible. Nothing pretends to be older than it is. The building is treated as something still in use rather than as a relic to be stabilised, which is precisely what it has been since 1228.

The tenant has changed again

There is a further chapter, and it confirms the argument rather than undermining it.

The retail operator that took the building after OMA handed it over, DFS, announced in November 2024 that it would close the store, and its lease expired in September 2025. After nine years, the department store chapter closed.

For most buildings that would be a difficult sentence to write. For this one it is simply the next entry on a long list. The Fondaco has outlived the German merchants, Napoleon’s customs officers, the Italian postal service and now a luxury retailer, and its 1508 plan has accommodated every one of them without being rebuilt.

That is the strongest possible endorsement of how OMA approached it. A restoration built around reversible insertions, public routes and revealed layers is a restoration that survives a change of tenant. Had the building been fitted out as a monument to one occupier, September 2025 would have been a problem. Instead the courtyard is still a covered campo, the escalators still climb, the corner rooms are still intact, and the roof still looks out over Venice.

The building is between uses, which is the condition it has been in, on and off, for eight hundred years.

Frequently asked questions

Final thoughts

The temptation with a building like this is to write about the frescoes as a tragedy and the restoration as a rescue. Neither is quite right.

Giorgione and Titian painted the outside of a warehouse. That is worth saying plainly, because it tells you what kind of building this was: the most important commercial address in Venice, decorated to match, by the best painters available. The frescoes were not a monument. They were a shopfront.

And a shopfront is allowed to change. What OMA understood is that the Fondaco’s value has never been in any single layer of it, but in the fact that a plan drawn in 1505 has absorbed eight centuries of different work without needing to be replaced. The right response to that is not reverence. It is another good layer.

A courtyard you can walk into. A route you can climb. A roof you can stand on. Painted walls, made now. And a building sitting quietly at the foot of the Rialto, waiting to find out what it is next.
